The height of a punted football can be modeled with the quadratic functions h= -0.01x^2+1.18x+2. The horizontal distance in feet from the point of impact with the kicker’s foot is x, and h is the height of the football in feet. How far has the ball traveled when it reaches a height of 6 ft? Explain why there is more than one answer.

Expert Solution

Mathematical explanation of 2 answers

Since the distance has been modelled as quadratic equation of height, it means there has to be 2 real solutions as the distance. Unless the height achieved is the maximum, there will always be 2 answers if there are real solution.

Game explanation of 2 answers

Every time football is shot (or hit), it goes to a high point and then come back down.

There are 2 points, for which height is equal situated either side of mid point (i.e. heighest point).

As a quarterback throws the football, it leaves his hand at a height of h and at an initial speed of v0 at an angle θ above the horizontal. The receiver can’t get to the football in time and it falls onto the field. What is the ball’s speed as it hits the ground? Solve this problem in two ways: (a) using kinematics, explicitly calculating the trajectory the ball takes (b) using conservation of (kinetic + potential) energy

In Week 4 we learned about quadratic equations. In physics a quadratic equation can be used to model projectile motion. Projectile motion can describe the movement of a baseball after it has been hit by a bat, or the movement of a cannonball after it has been shot from a cannon. A penny falling from the Empire State Building can even be modeled with this equation! The projectile motion equation is s(t)=-16t^2+vt+h where s(t) represents the distance or height of...
